NOVELTY - An anode material comprises spherical lithium-chromium-manganese oxide and graphene sheet inserted between the spherical lithium-manganese-chromium oxide at a mass ratio of 100:0.5-5, where the lithium-chromium-manganese oxide is lithium-oxide. USE - Anode material. ADVANTAGE - The anode material has better magnification performance, high specific capacity and long cycle life. DETAILED DESCRIPTION - An anode material comprises spherical lithium-chromium-manganese oxide and graphene sheet inserted between the spherical lithium-manganese-chromium oxide at a mass ratio of 100:0.5-5, where the lithium-chromium-manganese oxide is lithium-oxide (xLi2MO3.yLiM2O4.(1-x-y)LiMO2), x is more than 0 and less than 1, y is more than 0 and less than 1, 1-x-y is more than 0 and less than 1, and M represents manganese and/or chromium. An INDEPENDENT CLAIM is also included for a method for preparing an anode material.
